With the rapid development of current social electronic technology and control theory, the application of permanent magnet traction motors in rail transit vehicles is becoming more and more important. A permanent magnet traction motor applied to the next generation subway was studied, the scheme of the next generation subway permanent magnet traction motor was designed, the number of pole pairs of the permanent magnet traction motor were designed and choosed respectively, the motor rotor magnetic circuit structure and ventilation cooling structure were designed, and the air volume was calculated and simulated.Through data simulation analysis and calculation, the relevant parameters of the permanent magnet traction motor used in the next generation of subways were obtained. The research results show that the permanent magnet traction motor has the advantages of small size, light weight, large starting torque and good dynamic performance. It can achieve direct drive without gearbox for subway vehicles, and is widely used in rolling stock.
